Using energy from renewable resources is always a good thing. But while adding solar panels to your own home might be an option, renewable energy is harder to depend on while you’re traveling. If we want to explore out of our immediate areas, we’re still stuck in a world of airplanes, cruise ships and cars after all. That might be changing.

While we probably won’t be seated on a solar powered plane across the Atlantic anytime soon, solar power is being put to use in creative ways that could have big meaning for the travel industry. And not just in high tech backpacks.

This summer, 55-year-old Bertrand Picard has spent much of his time flying in his solar-powered HB-SIA, a prototype plane with the same wingspan as an Airbus A340. Created in Switzerland, Picard’s Solar Impulse Project came to the United States in recent months, crossing from San Francisco to New York City in five stages. The goal is for a world circumnavigation with the next generation of the plane in 2015.

Picard’s not the only one.Earlier this spring, Li Linxiang and his wife Zhao Yafan, a retired Chinese couple, set off to travel around the world on their own solar powered electric tricycle. They plan to make it through China, Kazakhstan and the Middle East before wintering in Ethiopia, and then enter Europe in spring 2014. Covering the entire globe? That will take them about five years.

And while these examples may seem a little off the wall, solar power is nowadays becoming accessible to hotel guests around the world. From China to Maine to Australia, hotels are opting to power their operations with the help of the sun, and designers are working hard to come up with new ideas of how to put solar power to good use, in the hopes of greening the travel industry. Beyond hotels, there are plenty other examples of solar power and tourism coming together. This summer, New York City installed solar powered charging stations for cellphones and if you choose the right cruise line, you can even end up on a ship employing solar technology, like Celebrity Cruise’s Solstice.

So while your next non-stop flight to Europe might not be fueled by the sun, keep an eye out for emerging technologies, and watch as hopefully more businesses in the travel industry put solar power to good use.
